    I like everything about this filter. The fact that the spout works very well with many different size bottles and whatnot is an added bonus.

      Comments about MSR AutoFlow Gravity Filter:

      The filter was easy to use. We used it for a group of eight and had no problems filling everybodys water bottles during lunch and dinner breaks on the AT. The water we filtered was clear taken from a mountain steam so I don't know how it works with murky water.

      Questions & Answers Powered by TurnTo®

      Questions about this item:

      Shopper  Will this filter out: 1. Bacteria 2. Chemicals / Toxins 3. Protozoa 4. Viruses ?
      STEVE D  The MSR AutoFlow Gravity Filter is an excellent backcountry tool. It quickly processes water, and is very simple to use. In North America, bacteria and protozoa are the most common challenges. This unit handles them, as well as sediment. The carbon component of the MSR filter will remove a great deal of chlorine and some VOCs (volatile organic compounds). Removing viruses requires more stringent filtration. If use in developing nations is planned, there are are other filters that would be advisable, such as a unit from Sawyer. For all use other than virus removal, the AutoFlow is awesome.
      Shopper  What is the amount of water this can treat before needing replacement?
      SunnySports S  The Cartridge life is 1500 liters. Stay safe and have fun out there! Neal
